Abstract
The utility model relates to a sealing element between relatively-stationary surfaces, specifically to an anti-blocked sealing ring, composed of a seal ring and a filter screen. The utility model is characterized in that the filter screen is arranged in the seal ring and the circumference of the filter screen is fixed by the seal ring. The utility model is anti-clogging, durable and safe and can be used for sealing the relatively fixed surfaces in motor cars, engineering machinery and machine tools, especially suitable for hydraulic and pneumatic systems.
Description
The utility model relates to the seal element between relatively-stationary, specifically a kind of anti-blocking seal ring F16J15/02.
As everyone knows, existing O RunddichtringO can only play single seal action, in hydraulic system and pneumatic process, if there are foreign material to exist in the medium, will cause the obstruction of hydraulic element and pneumatic element, phenomenon such as stuck, can cause interior accident when serious, influence the normal operation and the safety of whole system; In addition, not uniform or because of the pressure of sealing medium to the impacting force of seal ring, seal ring is easy-rupturing and the phenomenon of dielectric leakage takes place very.
The purpose of this utility model is to avoid the deficiencies in the prior art part, and a kind of safe and reliable anti-blocking seal ring is provided.
For achieving the above object, feature of the present utility model is to be provided with filter screen in the seal ring, and the periphery of filter screen is fixed by seal ring, and the material of seal ring can adopt nonmetallic material such as rubber, also can adopt softer metals, its section shape can be garden shape, also can adopt square, ellipse garden shape.Filter screen can adopt metal screen, also can adopt the synthetic fiber filter screen.
The utility model adopts filter structure, and filter screen encloses skeleton function to sealing, so have anti-plugging, advantage durable, safe in utilization.
Description of drawings:
Accompanying drawing is a kind of schematic representation of the present utility model, also is a kind of embodiment's schematic representation.
Fig. 1 is a plan view of the present utility model
Fig. 2 is a left sectional view of the present utility model
Below in conjunction with accompanying drawing the utility model is described further, as can be seen from the figure.A kind of anti-blocking seal ring is made up of seal ring 1, filter screen 2, seal ring 1 adopts rubber material, filter screen 2 adopts chain link fence, the periphery of filter screen 2 is fixed by seal ring, 2 pairs of seal rings 1 of filter screen play skeleton function, can improve the intensity of seal ring, the utlity model has the characteristics of anti-plugging, durable, effect safety.
